fix: apply link_filters property in List View standard filters

closes #34257

Problem

Link fields with link_filters property defined in DocType configuration were not being respected when creating standard filters in List View. This caused Link fields to show all available options instead of the filtered subset defined in the DocType metadata.

Root Cause: The make_standard_filters method in the FilterArea class was not including the link_filters property when constructing the filter configuration object from the DocField definition.

Solution

Added link_filters property to the config variable construction in FilterArea.make_standard_filters() method. This ensures that Link field filters defined at the DocType level are properly applied when rendering List View filters.

Changes Made:

• Modified FilterArea.make_standard_filters() to include df.link_filters in the filter config
• Link fields in List View now properly respect their configured link_filters property
• Filters are applied consistently between Form View and List View

Testing

Before:

• Link fields in List View filters showed all available options
• link_filters property was ignored in List View context
• Inconsistent behavior between Form View (filters applied) and List View (filters ignored)

After:

• Link fields in List View filters correctly apply link_filters property
• Filtered options match the DocType configuration
• Consistent filtering behavior across Form and List Views

Test Cases Verified:

1. Created a Link field with link_filters property in a custom DocType
2. Opened List View and added the Link field as a filter
3. Confirmed dropdown shows only filtered options (not all records)
4. Verified filter selection and application works correctly
